A two-decade family feud came to a violent end when a man shot dead the two home invaders that killed his wife and son, not knowing the assailants included his long-estranged daughter, authorities said Sunday.

Though the investigation of Friday's shootings continues, authorities said it appears Josephine and Jeffrey Ruckinger planned to murder her family at their rural central Pennsylvania home -- but it remains unclear what exactly led to the deadly confrontation.

"They parked at the bottom of a long driveway, and walked up, heavily armed," said Cambria County District Attorney Kelly Callihan.

Josephine Ruckinger was armed with a sawed-off 12-gauge shotgun and her husband had a Derringer pistol and a .22-caliber semi-automatic handgun as they approached the Frew family home in Ashville, about 40 miles southwest of State College, according to investigators.

John Frew, his wife Roberta, and their son John Jr., 47, had just returned from dinner out, and were watching TV in the living room of the white mobile home when there was a knock at the door, authorities said.

Police say Roberta, 64, answered the door, and cried out something like "Oh my God, they have guns!" before her daughter shot her at point-blank range. John Jr. then may have attempted to arm himself with a gun, but Jeffrey Ruckinger shot him multiple times in the chest, killing him, police said.

The elder Frew, 67, grabbed a .22 revolver and came out from the bedroom to find the daughter he didn't initially recognize pointing the shotgun at him. Frew fired once, hitting her in the head, then turned and exchanged fire with Jeffrey Ruckinger, killing him. He then called police.

I've said many times that you're just one bad day away from being just like the nuts we see on the news

I said last week that you're not much different than the Naval Yard shooter who was hearing voices and thought the government was bombarding him with ELF waves

Is that so much different than the insane delusions you post on this board ?

Imagine how many times they will play your pathetic public humiliation at the baseball game over and over after you finally snap. Same goes for you lame walkout on the Today show. By that time they will have matched up your 333 and Soul Crusher personas (yes, now someone will actually care to look) and they will be astonished that the simple minded oaf that was in their studio was actually an insane person on the brink of a meltdown

Man I hope youre charging 333 rent for all the space he occupies in your noggin.

Hmmmm....new idea for a reality show? Bitter enemies on an internet forum meet up in person for a romantic dinner.......hilarity ensues.

Perhaps the dinner will be an Obama $50,000 a plate benefit.....I can see it now:

Straw on her dirty knees groveling on the floor screaming in a Wayne's World-esque litony "I'm Not Worthy! I'm Not Worthy!" Then proceeds to pass out from a sheer rush of ecstasy like a Third World kid seeing Michael Jackson for the first time.

Soulcrusher begins to foam at the mouth and is immediately apprehended by the Secret Service. In fact, I think I hear some black Chevy Suburban doors slamming closed right outside his Bronx flophouse.
